JOSEPH "I-IASLAM 1n his lifetime l, .didf invent Thread of `OneMaterialiwithlafCoating of a` Dierentl Material by WhichCertainUse fulResults `are Secured; and we further de- "clarethat the followingspeciication, taken 11s. j in connection` lwithl-thedrawings, `is a fulla and gexact" descriptionfof the invention of saidJosErrrHAsLAMu iInmany bf" textile fabrics a fine `surface or onecomposedofcostlylmaterial is a desideratum, but the interior part of the fabricmay be `composed of aless costly material, not onlywithoutinjury to thefab- "rcfas a wholeubut even" to its benefit." A

coarse `and "strong interior would tend to the durability of the articleand would moreoverenablelthe manufacturer to afford it at 'a less priceevenwhen 'more material was "employed andathicker, warmer andmoredurable fabric "wasithe result.` `This object f1 has been attainedbyemploying `threads of f `a cheaper material whichfin the process ofweaving wereqthrownbeneath the Vsurface a orf at any rate appearedthereon only f slightly and it hasalsobeen attempted by whollyfcovering,each particular thread of cheap material'with a coating of a morep`costly one.` Thislatter idea has from imperfection of the processinthe one* method 1 or from its great costin another plan .been l.hithertopractically unsuccessful.` By the former` method it was essayed to take`a ffrollfof the `fine materialdirectly from the carding machine andwiththis cover a hard thread. The failure" arose probably from the want oftenacity of the covering which therefore tended to apply itself inlspots`instead ofbeing diffused yequally over vthe l `whle surface of theinner thread.

of suchA a The nature of 1J osEPH HAsIaaMsinven-` "tion consists incovering a thread of one` material. with other material applied there- 1to" either as: aroving or as a slacktwisted yarnhandalsoen beddingtheformer intox `l the "latteriprior"toLtwisting` the two together: For*this purpose he` availedv himself. of well known "machinery of any usualkind the essentials," thereof being drawing rollers and a flier andbobbin or their equivalents.

` In his process a roving or a loosely twisted thread either in a can oron a bobbin and prepared either in a drawing or a throstle frame or inany well known way is passed through drawing rollers, or through asingle pair of rollers only on its way to` a flier, while a harderthread of less costly material taken from a. bobbin, cop or otherwise ispassed through the same `rollers or some of them, in such manner`thatfthe latter is guided so as to pass through in contact with thecenter of the former or nearly so, and is by the pressure of the rollersbedded into it. The, combined threads then pass to a flier which twiststhe mass and completely cover 4the one material with the other, thecoating being equable and its thickness being regulated either bytheoriginal size of the roving or yarn, or by the reduction thereof durinits passage through some of the drawing ro lers `before itf comes incontact with the inside thread.

In the drawings a machine fit for per` formin this pro-cess isrepresented. In the beneath the'table. The apparatus for moving theserollers is not represented in the drawing: through all these rollerspasses theroving o from the can d, or if a loosely twisted yarn beemployed, it follows the same track and is supplied from a bobbinoccupying `thesa-me position as can d. A

Ihard thread of coarse material wound Aon bobbin e passes through theguiding eye f,

over rollers a2 and a3 and between rollers rame are represented threesets of l a a where it is bedded into c c, the two threads then enterflier g, and after being twisted together are deposited upon the bobbinh. i

It will be perceived that the thread of coarse material travels overrollers a2, and a3 in a direction contrary to their motion. This courseputs a drag on the thread previous to its entry between rollers a a andinsures its being bedded in the roving or loosely twisted thread.

It is apparent that the form and number of parts in the apparatus may bematerially varied, while it is still applicable to lthe processdescribed and also that well known equivalents of these parts may beused in place thereof to secure an equally good result.

This process is chiefly applicable to the covering of cotton with wool,or silk but is useful also for covering coarse wool. with line, and weintend by means thereof to make a substitute for satinets and all thosegoods which are composed at present of mixed materials in distinctthreads.

We claim as of the invention of JOSEPH HAsLAM deceasedi The method ofbedding one thread into a roving, or loosely twisted thread of anothermaterial, as also the covering of one thread b a roving or looselytwisted thread of a di erent material, substantially in the manner andfor the purposes herein set forth.

In witness that the foregoing is a true description of the invention ofsaid JOSEPH HALSAM deceased we have hereunto set our V hands in the cityof New York county of New York State of New York on this ninth day ofNovr. 1854.
